The Inhibitory Effect of Peptide Hydrolysate of Type I Collagen Derived from Pig Skin on Melanogenesis in B16F10 Melanoma Cells.

ABSTRACT: Collagen peptides, as a natural source of peptides, possess multiple advantages such as anti-aging, anti-inflammatory properties, tissue repair, and the ability to inhibit melanin production. In this study, type I collagen extracted from pig skin was hydrolyzed with 1% and 3% hydrochloric acid, yielding collagen peptides CPH1 and CPH3. The melanin content and tyrosinase activity in B16F10 cells were compared via direct and paracrine action when CPH1 and CPH3 were used to interfere with melanogenesis. It was found that CPH3 significantly inhibited melanogenesis in B16F10 through the paracrine action involving HaCaT keratinocytes. The intracellular melanin content was measured at 65.23 ± 1.30%, and the mRNA levels of tyrosinase and microphthalmia transcription factor in cells were 55.77 ± 6.
